Application filed July 14, 1905. Serial No. 269,636.

This invention relates to iireproof windows having metallic casing and sash constructions and in which the sashes are arranged to be raised and lowered in the usual manner and also to be swung inward on vertical axes for the purpose either of ventilationwor to facil-i#f tate access to the eutersurfaces of the panes for cleaning them.

One of the objects of this invention is to provide a structurein which the verticallyan elevation of a window casing an `embodying my invention, parts being indisliding "hinge parts are entirely concealed from view and protected from liability of interference or damage from external objects. Another `obj ect is the provision of combined guides and'weather-strips for the sashes.

Another object is to facilitate the inward swin ing dr removal of the sashes by mount ing `t e guides and weather-strips on one side, so that they can be conveniently shifted or moved bodily away from the sashes or into 4the casings.

To these ends the invention consists in the construction and combination of arts, substantially as hereinafter describe and claimed.

0f the accompanying drawings, Figure 1 is sashes cated by dotted lines and a portion of one side of the casing being broken away. Fig. 2 represents a section, enlarged, on line 2 2 of Fig. 1 lookin down and indicatingby dotted lines a partial open position' of the lower sash. Fig. 3 is a view similar to 2, but illustrating a modification of the siding base members of the hinges. Fig. 4 is a detail `view similar to a ortion of F1 2, but illustrating another modification in t e form of and su pprt for the sliding base members of t e nges , Similar reference characters indicate the same or similar parts throughout the several views.

The upper and lower sash-frames are represented at 10 and 11, respectively, said frames being made of sheet metal in a well-known or referred manner, as are also the casing 12 or the hinged side of the sashes, the casing 13 for the free side of the sashes, the top casing 14, and the sill 15. Portions of these frames are casings, however, and are given a novel shape to guide the sashes in their vertical movements, as will be described hereinafter.

Suitable eounterweights (indicated at 16) Patented .April 3, 1906.

are connected A.by cords 'or chains"17,` running over pulleys 18, (see dotted lines in Fig'. 1,) with the sash-frames in any suitable manner. In Fig. 2 the top rail of the lower sash-frame is shown as formedwith-heles-19,-into which may biitted-the Shanks of eyebolts attached to the ends of the counterweight cords or chains. The other sash-framesl may be connected with their cords or chains in the same manner. As the counterba'lane-ing` `of the sashes forms no l have not attem ted to illustrate or describe the same in detail) i In the referred form of my invention (shown in igs. 1 and 2) the hinges are constructed as follows: Each hin e comprises a leaf 20, suitably secured to t eface of the left-hand side of the sash-frame, the ears of said leaf which carry the pintle 21 extendin close to the inner Wall of the casing 12, Whic is vertically slotted, as at 22. The inner leaf 23 of the hinge extends through said slot and is formed with a head 24, said head being in the form of a short vertical cylinder. Within the casing 12 'are secured two vertical c lindrical guides 25, one for the heads 24 of the hinges of each sash. Each guide 25 has wings 26, terminating in foot-flanges 27, suitably secured to and against the inner wall of the casinilr 12. The two leaves of each hinge part of my present invention,

are fiatthat is they are in a uniform plane-- when the sashes are in the position shown by fulll lines in Fig. 2. Therefore there is no liability of any torsional movement that might tend to bind the inner leaves and their heads in the guides. Moreover, the joined ears of `the hinges are close to slotted Wall of the casing 12, and the leaves 20 are so located as to be readily and conveniently secured to or separated from' the sash-frame. The guides for the headed leaves are entirely concealed Within the casing 12 and protected thereby from risk of being dented or bent out of true, and therefore they may be practically made of comparatively thin sheet metal. 'Furthen more, the flanges 27 of the guides extending the full height of the casing 12 and secured to' the inner wall thereof strengthen and reinforce the latter. To relieve the hinges from IOO IIO

. guides;

' carried b 13, said the duty of guiding the sashes in their vertical movements, the inner wall of the casing 12 is bent to form vertical grooves or chan nels 28, which are V-shaped in cross-section, and the outer wall of each sash-frame at the hinged side thereof is bent to form vertical ribs 29, corresponding in shape to the channels 28 and fitting therein. Said ribs and channels also serve the function of weatherstrips at that side' of the sash-frame.

The glass panes of the sashes are indicated at 30, -the edges of said panes resting in grooves in the frames and secured by putty or cement 31. The said panes may be set in pla'ce or if broken replaced by new ones by removing Yone of the sash-rails in any wellknown manner. rIhe special structure of the sash-frames to permit this need not be illustrated or described herein, as it forms no part of this invention.

..lhe' outerwface ofeachsash-frame at the right or free side isbent to for'a'vertical groove or channel 32, which is V-shaped 1n cross-section. The window-casmg 13 is pro- -vided with combined Weatherstrips and 'which are preferably composed of strips of sheet metal bent to a sha e corres vonding with the grooves 32, as in icated in Iii s. 2 and 3, and fitting said grooves sufficiently closely =to serve the purpose of weather-strips and also to form guides at the ri ht for the vertical movements of the sashes. T ese angular weather-strips are indicated at 33, and they are mounted in vertical slots or guides34, formed in the inner or front wall of the casing 13,V soV as to be projected more or less from said casing or to be withdrawn into the casing when a sash is to be swung inward to the dotted-line position shown in Fig. `2. Any -suitable means may be provided for moving or shifting said strips, and I do not limit myself to any specific mechanism or devices for this purpose. The means which I have preferred to illustrate however, comprrise rack-bars 35, secured to and projecting om the strips into the casing 13 and engaging and partially supported by pinions 36, shafts 37; mounted in the casing s afts having handles or crank-arms 38 outside of the casing. By means of said cranks the'shafts and pinions may be actuated so as to retract t e strips 33 from the position shown in Fig. 2 in a manner that will be readily understood to clear the stri s from the angular channels 32 to enable t e sash or sashes to be swung inward when desired. Since the upper sash can be and preferably is lowered before swinging it inward, it is not necessary to rovide for the retraction of the entire gui e and weather strips.

In Fig. 1 the strip is indicated by dotted linesas composed of two sections in alinement with each other, the point of meeting of the two sections being preferably slightly above the top rail of the lower sash when the latter is shut down. To distinguish the two sections, the upper one is indicated at 330 and the point of meeting of the two sections at 331. The upper section 330 may be fixed or held rigidly by any suitable means in posi.- tion to closely fit in the vertical channel of the upper sash-frame. When it is desired to clean the outer surface of the upper sash, the lower sections 33 of both guide-strips for the twosashes are first retracted into the casing 13, the weight-'chains detached from the free side of each sash, the lower sash then swung inward, and the upper'sash lowered to clear the lower end of the upper fixed strip-sections 33() and then swing inward on its hinges. After reversing this operation and again projecting the lower strip-sections 33 into alinement with the upper sections 330 the two sashes` may be moved vertically in the ordinary manner.

As represented in Fig. 3, the inner leaves 23 of the hinges ma T be provided with heads cplnsistihg of flange portions 240, bent latera Y cylindrical members, as shown inv Fig. 2. Theseflat heads ride vertically against the inner faces of strips 270, securedinside the wall of the casing 12, said strips serving to reinforce said wall in the same mannekes the flanges 27 in Fig. 2. In both constructions the guides for the sliding members of the hinges act also to reinforce the front or eX- posed wall of the casing 12, and the same is v true to some extent of the construction shown in Fig. 4, in which a single sash is partially represented. In this form the inner leaf of the hinge is formed substantially the same as represented in Figs. 1 and 2 3 but the cylindrical Guide 25 is secured in a vertical recess 39, formed in an outwardly-bent portion of the wall ofthe casing 12. In each form shown the portion of the hinge-leaf which connects the sliding head with the intle ofthe hinge is hat or straight, (no bends occurring therein,) and therefore there is no'tendency to bind or cramp the sliding head relatively to its guide, whether the sash is swung on its hinges or not, and also in each form the ears of the two leaves which inclose the intle slide close to the slots through whic the leaves 23 extend and prevent any inward movement-of the heads relatively to their guides.

The casings 12 and 13 are shown as formed with bent ortions 40, which overlap the margins of the upper sash and form beads or stops which prevent said sashfrom passing outward beyond its proper position when returning itfrom an inwardly-swung position.
